REUBEN W. DREW, OF CLEVELAND, OHIO.

LUBRICATOR.

SPECIFICATION forming part of Letters Patent No. 242,119, dated May 31, 1881.

Application filed April 15, 1881. (No model.)

.To all whom t may concern:

Be it known that I, REUBEN W. DREW, of Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in -Lubricators 5 and I do hereby declare that the following is afull, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawin gs, which form a part of this specication.

Figure l is a perspective view. Fig. 2 is a perspective view, showing a modification. Fig. 3 is a vertical sectional view of the device shown in Fig. 1. Fig. 4 is a detail view ofthe same. Fig. 5 is a vertical sectional view of the device shown in Fig. 2, and Fig. 6 is a detail vieu7 of the same.

Corresponding parts in the several igures are denoted by like letters of reference.

This invention relates to lubricators for various kinds of machinery 5 and it consists, especially, in certain improvements in the top cap or plate, by which means are provided for feeding oil to the lubricator Without removing the said cap or plate, and in a more convenient manner than th at heretofore practiced.

My invention is capable of being applied to lubricators of any well-known construction; and it consists in the peculiar construction of the top plate, and the combination, with the same, of a pivoted or oscillating head-plate havin ga h andle and suitableopenings, through which the lubricating-duid may be fed.

In the drawings heretoannexed, A represents the body or bulb of the lubricator, and B the top or cap plate of the latter, which is provided -With a suitable bearing or box, C, for the rod or device, by which the oW of the Vlubricant is to be regulated.

The box C is provided with a collar or dan ge, D, by which a bearing is formed fora disk, E, capable of being oscillated in a horizontal plane by a handle, F, with which it is provided.

'Ihe disk E is provided with a feed-opening, G, which may be adjusted over a corresponding opening, H, in the top plate, B, of the 1ubricator. The said plate B is also provided with a vent-opening, I, which registers with a similar opening, J, in the disk E when the openings G H are in juxtaposition.

The disk E is to be provided with a handle, K, by which it may be readily adjusted to its proper position, and the cap-plate B may be provided with pins or studs, as shown in Figs. l, 3, and 4, to conne the motion. In the remaining figures I have shown the cap-plate B provided With a flange, L, having a recess, in which the handle K may move, the openings for the admission of the lubricant being arranged as above described. In this case the said :dange serves as a guide to prevent overflow or waste of the lubricating-fluid when poured into the bulb or cup.

The plate B is provided, adjoining the opening H, with an inclined notch, N, through which, when the plate E is partly turned, a small current ot' air will enter, thus facilitating the feed ot' the lubricating-duid.

The operation ot my invention Will be readily understood.

The top disk, E, may be readily turned so as to expose the opening through which the lubricant may be fed to the cup, the registering vent-opening being at the same time exposed.

The feed-opening may be entirely closed, or so` adjusted as to leave a. vent-opening of any desired size through the notch N.

Having thus described my invention, I claim and desire to secure by Letters Patent of the United StatesrThe combination, in a lubricator, of the capplate B, having opening H, and adjoining notch N, with the oscillating plate or disk E, having feed-opening G, and handle K, as herein described, for the purpose set forth.

In testimony that I claim the foregoing as my oWn I have hereto aiiixed my signature in presence of two witnesses.

REUBEN W. DREW.
